Alternate costume (SSBM)

NOTE: Every claimed source needs a cross-reference link; claimed sources need to be plausible, not horrendously obscure; default costumes usually don't need descriptions since they are not alternate costumes; returning costumes original to Smash do not need references to their appearances in previous Smash games.

A battle between four Dr. Marios, each one in different colored lab coats.

Pichu’s alternate costumes.

Super Smash Bros. Melee added additional alternate costume options to characters by using the and buttons to cycle through the available list instead of using four to pick a specific color; this removes the limit as to how many are selectable, so there are no longer any costumes exclusive to Team Battles or computer opponents. As a result, many characters now have five different color schemes, with some having as many as six, though some still only have four, leading to a total of 123 alternate costumes in the game.

When selecting characters in Tournament Mode, instead of displaying the character's colored image of the chosen costume, the character's name is given a tint and a colored bar is displayed in the player list. This color is usually an intuitive indicator of which costume has been chosen (with white denoting default), with actual white costumes being denoted as gray.

In Team Battle, if members of the same team use the same character, the second player would have a lighter tint applied to their character. A third player uses a darker tint. If a fourth player is forcibly added to a team with the Name Entry glitch, then the fourth character will be completely black; the game's data suggests that a fifth player, if possible, would be completely gray. A sixth player would be completely pink. A seventh player and afterward, would crash the game, additionally it is not possible to view the completely pink character unless additional Action Replay codes are used.

Strangely enough, alternate costumes can affect gameplay, such as Captain Falcon's model changing sizes depending on the costume.
